Verified step by step guidance

Understand the nature of the Hepatitis C virus (HCV): HCV is an RNA virus, not a DNA virus, which means it does not integrate into the host genome like some DNA viruses do.

Consider the transmission routes of HCV: HCV is primarily transmitted through blood-to-blood contact, not through respiratory droplets. Common transmission methods include sharing needles or other equipment to inject drugs.

Evaluate the prevention methods for HCV: Currently, there is no vaccine available for Hepatitis C, unlike Hepatitis A and B, which have effective vaccines.

Recognize the potential outcomes of HCV infection: If left untreated, HCV can lead to chronic liver disease, including cirrhosis and liver cancer, which is a significant health concern.

By process of elimination and understanding of HCV characteristics, identify the true statement: 'HCV can lead to chronic liver disease if left untreated' is the correct statement.
